<p>Model:数据,其实就是angular变量($scope.XX);</p>
<p>View: 数据的呈现,Html+Directive(指令);</p>
<p>Controller:操作数据,就是function,数据的增删改查;</p>
<h3 id="2-2双向绑定"><a href="#2-2双向绑定" class="headerlink" title="2.2双向绑定"></a>2.2双向绑定</h3><p>AngularJS是建立在这样的信念上的：即声明式编程应该用于构建用户界面以及编写软件构建，而指令式编程非常适合来表示业务逻辑。框架采用并扩展了传统HTML，通过双向的数据绑定来适应动态内容，双向的数据绑定允许<strong>模型和视图之间的自动同步</strong>。因此，AngularJS使得对DOM的操作不再重要并提升了可测试性。</p>

<h3 id="2-3依赖注入"><a href="#2-3依赖注入" class="headerlink" title="2.3依赖注入"></a>2.3依赖注入</h3><p>依赖注入(Dependency Injection,简称DI)是一种设计模式, 指某个对象依赖的其他对象无需手工创建，只需要“吼一嗓子”，则此对象在创建时，其依赖的对象由框架来自动创建并注入进来,其实就是最少知识法则;模块中所有的service和provider两类对象，都可以根据形参名称实现DI。</p>

<p>ng-app 指令 作用是告诉子元素一下的指令是归angularJs的，angularJs会识别的</p>
<p>ng-app 指令定义了 AngularJS 应用程序的 根元素。</p>
<p>ng-app 指令在网页加载完毕时会自动引导（自动初始化）应用程序。</p>
<p>ng-model 指令用于绑定变量,这样用户在文本框输入的内容会绑定到变量上，而表达式可以实时地输出变量。</p>
<p>我们如果希望有些变量具有初始值，可以使用ng-init指令来对变量初始化</p>

<h3 id="5-2前端"><a href="#5-2前端" class="headerlink" title="5.2前端"></a>5.2前端</h3><p>主要思路：我们需要定义一个用于存储选中ID的数组，当我们点击复选框后判断是选择还是取消选择，如果是选择就加到数组中，如果是取消选择就从数组中移除。在点击删除按钮时需要用到这个存储了ID的数组。</p>
<p>这里我们补充一下JS的关于数组操作的知识</p>
<p>（1）数组的push方法：向数组中添加元素</p>
<p>（2）数组的splice方法：从数组的指定位置移除指定个数的元素 ，参数1为位置 ，参数2位移除的个数 </p>
<p>（3）复选框的checked属性：用于判断是否被选中</p>
